Let's divide 453012 by 25
Our goal is to divide 453012 by 25.

Advancing to step 1:
If we divide 4 by 25, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 25

Going ahead to step 2:
When dividing 45 by 25, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 25 from 45 and we're left with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 25

Advancing to step 3:
When dividing 203 by 25, we get 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 200 from 203, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 25

Step 4:
25 can be fit into 30 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 181.0
The remainder is 5 after subtracting 25 from 30.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 25

Let's proceed to step 5:
25 goes into 51 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1812.0
Subtract 50 from 51 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 25

On to step 6:
25 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 18120.0
Deduct 0 from 12 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 25 fits into 120 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 18120.4
If we subtract 100 from 120, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 25, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 18120.48
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18120.48
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18120.48
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 18120.48 with a remainder of 0.0.
